(((The fantastic difficulties of confronting technology without a property regime.
The stuff we've got isn't "techne" as the ancient Greeks defined it, but a huge technosocial snarl that probably deserves an ungainly name like "intellectuo-techno-propertarianism.")))
(((And if you think Open Source is quixotic and complicated, you oughta ponder its mostly-imaginary, aggressively communist anarcho-punk little sister, "Autonomous Commons.")))

(((I'm trying to imagine eating a carnitas burrito that didn't involve any patents. I dunno, maybe if you grew the pigs in the back yard of an outlaw tin favela shack and then brained them with a homemade stick.)))
It's a 6-layer burrito
Hardware / Mechanical Diagrams
Dimensions for enclosures, mechanical subsystems, etc. For 2D models, preferred document type is vector graphics file, with dimension prints, DXF, or AI, etc. Materials. RepRap - motor drive screw block, open source 3D printer.
Schematics & Circuit Diagrams
Symbolic diagrams of electronic circuitry, includes parts list (sometimes inclusively). Preferred document type is any sort of image (PDF, BMP, GIF, PNG, etc). Often paired with matching layout diagram. Chumby - Power supply, open source beanbag computer.
Parts List (BOM)
What parts are used, where to get them, part numbers, etc. Ideally - have data sheets, generic, easy to get, notes and specifications. No f***ing (((sorry Ada, but I gotta feed the spiders here))) NDAs please. Standard format is a text file, BOM (bill of materials). Often included with or part of the Parts list from the open source Roland 303 MIDI synth schematic. clone, the x0xb0x.
Parts lists from the open source embedded Asterisk IP PBX http://www.rowetel.com/ucasterisk/hardware.html http://svn.ast�n.org/hardware/ip04/trunk/ip04_bom.xls
Layout Diagrams
Diagrams of the physical layout of electronic circuitry, including the placement of parts, the PCB copper prints, and a drill file. This is often paired with a schematic. Preferred distribution is Gerber RS274x and Excellon (for drills). These are like PostScript for printers but the primitives aren’t text and arcs, they’re lines of solder and components. Make: Daisy - Open source MP3 player.
Core/Firmware
The source code runs on a microcontroller/microprocessor often in C, Assembly. In some cases, the code may be the design of the chip hardware itself (in VHDL/Verilog/RTL, etc…). Preferred distribution: text file with source code in it, as well as compiled ‘binary’ for the chip. Language and architecture is irrelevant. Open core 8080 compatible CPU code snippet from executing the 8080 instruction set.
Software/API
The source code that communicates or is used with the electronics from a computer (if applicable). Any drivers necessary for the chipset. Preferred format is source code and binaries. We don't think tools count. Arduino IDE... (((etc etc etc well at least Lady Ada's got a real working enterprise here, because I've been to see the office, and they built the thing from the smoldering rubble of Wall Street.)))
